This wallet is great for a 4 outs if you need one. You can put in cards or notes or any other flat things. you can show the wallet empty after pulling out the card half way out and letting the spectator pull it all the way out and look into the empty pocket.
You can not give the wallet for examination, but there is really no need for that.
Compering it to Number 4 envelope, you can say it about the same thing but on steroid and it look better, I got the two of them, but handling the wallet is more easy to manage.

Although similar to the "WOWallet" by Stephen Tucker, "Quatro Wallet" is not the same in fact it is more of a leather version of Blake Vogt's "Number 4 Envelope" which I found to be fantastic, but the audience found to be suspect. After one performance I stopped using it. I really needed four outs for a playing card and although after weeks trying make my own. I did manage to create a poker card sized version of what was a dead ringer for "Fourvelope" by Sensio, but the poker card size version was far more suspect and I never used it either. I have even been tempted by Scott Creasey's "Empty Multiple Out Envelope" download, and I am still curious about it, but I opted for "Quatro Wallet"

Before digressing entirely from the subject of creativity and invention. Most magic is like music, even what appears to be entirely original it is derivative, even if the current inventor believes it is their own original idea "Which came first the tribble or the flat cat?" Were those little fur ball toys my mother made for charity (who never watched Star Trek or cared for Science Fiction) stolen, or were they just cute fur balls my mother made for charity. I know she never credited Heinlein or Gerrold to be sure. If she had gotten the idea from either, I believe she would have in good faith credited them. However we must also accept the notion that some omissions are not due to the absence of good faith recognition, but not an omission at all. Good ideas and inventiveness are not not necessarily unique to any one induvial. There are generational idea streams that emerge from changes in technology where inventors oceans apart will have similar epiphanies.

We as magicians need to accept in good faith that our peers are being truthful and honest unless they have proved otherwise. Magic has gotten so derivative over the years, and has gone through so many incarnations, that it has gotten increasingly difficult to acknowledge all who came up with a similar idea before without hiring a historian.

Since I have not tested Scott Creasey's "Empty Multiple Out Envelope" I cannot add it to my comparison, but as for the others and as a four way outs for playing cards, the "Quatro Wallet' is my current choice.

To be perfectly honest, I would rather not have to go to a four way out with playing cards and I tried to perfect the one effect I insist upon doing and until I do not need one. Maybe someday. Until someday comes the "Quatro Wallet" is it. It in my opinion has less heat on it and works the best with pasteboards.

This is exactly wallet from Steven tucker, this is a great wallet made by Steve tucker, but it was stolen from Steven tucker, I don't like that there are robbers in magic industry and taking credits from other, as same as stolen lands and be the owners of something not yours.
⛔ shame on you Eran , you're a bad guy.
